Title:
  usb passthrough not working anymore

Status in QEMU:
  New

Bug description:
  Hi,

  I'm using qemu 2.0.0 with opensuse 13.1 x84_64 bit as host and window7
  as guest. Til qemu version 1.6.2 USB passthrough works perfectly, but
  starting with qemu 2.0.0 passthrough stop working. I can still add the
  usb device but when I start the guest following message appears:

  "unable to execute QEMU command 'device_add': 'usb-host' is not a
  valid device model name"

  Then the guest will not start.

  I try it with different usb devices (iphone, stick, hdd), always the
  same error.

  Are there any news / hints about this ?

  Regards

  Martin
